Question

Can we store concentrated solution of sodium hydroxide in a zinc container ?

Answer 1

(i) Sodium hydroxide solution cannot be kept in aluminium containers.

(ii) Silver metal does not combine easily with oxygen but silver jewellery tarnishes after some time.

(iii) Sodium is obtained by the electrolysis of its molten chloride and not from its aqueous solution.

(iv) Aluminium reacts with dilute hydrochloric acid slowly in the beginning.

Answer 2

Yes as sodium is more redycing than Zn.
so Zn won't be able to displace Na from its solution.

Hope my answer helps you.
